I have a float (table) which contains several subfloats. The last of these subfloats does not fit on the page and is cut off. I would like it to extend to the next page. I know of longtable but that does not work with floats in LyX. What is the right solution here?

longtable doesn't float at all it's not a lyx restriction. If you have that many floats can not they be separate floats rather than subfloats, a float is like a minipage and never breaks over a page.

@DavidCarlisle: well this is a table with several panels that relate to each other and so i wanted to keep them together. the reason i use floats is because the tables are actually TeX code that i simply paste into an ERT box in lyx

if you have a way to make this work in lyx without floats that works too
